The Advanced Sector Protection/Unprotection feature disables or enables programming or erase operations
in any or all sectors and can be implemented through software and/or hardware methods, which are
independent of each other. This section describes the various methods of protecting data stored in the
memory array. An overview of these methods in shown in
